Hold-Up Time (hold-up time)
Hold-Up Time is a bridging time that describes the period during which the specified output power continues to be provided in the event of an input voltage failure. Even normal power supplies can bridge short-term power failures up to the range of seconds by means of appropriately dimensioned input storage electrolytic capacitors. The Corsair HX1500i’s bridging time is long enough, and the power-ok signal is accurate.
Timings
The power supply also supports alternative power saving modes!
Inrush current (starting current or inrush current)
All power supplies generate a so-called starting current, which often exceeds their nominal current consumption by far. The causes are the charging of the different capacitances in the input circuit and in the EMC filters, the build-up of the magnetic field in the transformer core and even the charging of the capacitors in the output filter. Only when the converter is operating stably does this input current drop back to normal values. specific The inrush current of the Corsair HX1500i is low at 115 V, but quite high at 230 V.
